Product details
Overview
TLE4966GE6710HTSA1 from Infineon Technologies is a high-precision bipolar Hall-effect switch IC with integrated dual Hall probes for simultaneous speed and direction detection. It operates from 2.7 V to 24 V, delivers digital Q1 (direction) and Q2 (speed) outputs with 1.45 mm Hall plate spacing, and features active error compensation for mechanical stress immunity-used in automotive crankshaft and camshaft position sensing.
For engineers reviewing the TLE4966GE6710HTSA1 datasheet, TLE4966GE6710HTSA1 pinout, TLE4966GE6710HTSA1 application, or TLE4966GE6710HTSA1 equivalent, key selection criteria include magnetic switching point stability over temperature (±0.5 mT drift), low jitter (1 µs typ.), reverse battery protection (−18 V), and PG-TSOP6-6-9 package compatibility with SMT assembly.
Technical Context
The TLE4966GE6710HTSA1 integrates two chopped Hall probes with matched sensitivity and fixed 1.45 mm spatial separation to enable differential direction detection. Its on-chip oscillator drives chopper stabilization, while bias and compensation circuits maintain switching point accuracy across −40 °C to +170 °C ambient.
Direction output (Q1) transitions before speed output (Q2) within each magnetic pole pair cycle, enabling deterministic edge alignment for timing-critical engine control units. The device uses internal hysteresis comparators and reverse-polarity protected voltage regulation to tolerate unregulated automotive battery rails.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Hall-effect speed and direction sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX92292ESE-AAA-000-RE | Dual-output Hall sensor with programmable sensitivity; no integrated reverse battery protection | Requires external TVS and reverse polarity circuitry; higher design overhead for automotive battery interface | Preferred when field strength varies widely and dynamic threshold adjustment is needed |
| TLE4964-2K | Single-output Hall switch (speed only); lacks direction channel and Q1/Q2 phase relationship | Cannot resolve rotation direction-requires secondary sensor or mechanical differentiation for directional applications | Selected only for cost-sensitive non-directional speed sensing where Q1 functionality is unnecessary |
Compared with MLX92292ESE-AAA-000-RE and TLE4964-2K, the TLE4966GE6710HTSA1 uniquely integrates direction detection, reverse battery protection, and active error compensation in one PG-TSOP6 package-reducing BOM count and validation effort for AEC-Q100-compliant engine management systems.

FAQ
What is the purpose of the three GND pins on the TLE4966GE6710HTSA1?
The three GND pins (pins 2, 5, and 6) serve distinct functions: pin 2 is the primary analog ground for the Hall core and bias circuits; pins 5 and 6 provide dedicated return paths for digital outputs and enhance thermal conduction through the exposed pad. This multi-GND architecture reduces ground bounce and improves ESD immunity in noisy automotive environments.
Does the TLE4966GE6710HTSA1 require an external capacitor on the VS pin?
No external capacitor is required on the VS pin. The device integrates internal regulation and filtering sufficient for stable operation across its full 2.7–24 V range. However, a 100 nF ceramic decoupling capacitor placed near the VS pin is recommended to suppress high-frequency noise from the battery rail and improve EMC performance in production ECU designs.
How does the TLE4966GE6710HTSA1 achieve direction detection without external magnets or shielding?
Direction detection is achieved intrinsically via the fixed 1.45 mm spatial separation between its two on-die Hall plates. As a ferrous target moves past the sensor, the leading Hall element detects field change first, generating the Q1 (direction) pulse ahead of the Q2 (speed) pulse from the trailing element-no external components or magnet orientation adjustments are needed.
Is the TLE4966GE6710HTSA1 compliant with AEC-Q100 Grade 0?
Yes-the TLE4966GE6710HTSA1 is qualified to AEC-Q100 Grade 0 (−40 °C to +170 °C operating temperature), including stress testing for HTOL, TC, and ESD. The datasheet specifies operation up to +170 °C ambient and survival at +195 °C peak, meeting the most stringent automotive under-hood qualification requirements.
